About a month ago I had unprotected sex. 3 days later i had it again but then started bleeding. Littely at first, then went to a heavy flow that lasted about a week. Heavy cramping. This was about 2 weeks before my normal period on the 6th. But now it's over a month later (by a couple days),I have cramping but no period. I'm starting to worry. I have a lot of stress going on right now (break up, job search, sick child, bills) that could be why it's delayed. I don't feel nauseas or anything. Just crampy. And I just realized I'm late. Now I'm half freaking out.
